Attitudes and access to resources and strategies to improve quality of radiotherapy among US radiation oncologists: A mixed methods study
ConclusionPotential opportunities to improve radiation contour quality include improved access to disease-site specialists and contour-specific peer review. Physician time must be considered when designing new strategies. (Source: Journal of Medical Imaging and Radiation Oncology)

Adjuvant nodal field radiation in resected Stage III melanoma: A single ‐centre retrospective study in Christchurch, New Zealand
ConclusionPatients treated with adjuvant radiation remain at moderate risk of regional and high risk of distant relapse, despite the use of modern radiation techniques. Adjuvant radiation was associated with improved local control but infield recurrence rates remained a problem. The role of combined adjuvant radiation and immunotherapy in improving these outcomes requires further investigation. (Source: Journal of Medical Imaging and Radiation Oncology)

Iodinated contrast media shortage: insights and guidance from two major public hospitals
ABSTRACTGlobal shortage ofiodinated contrast medium (ICM) is the latest healthcare ripple-effect from the Covid-19 pandemic. Some public hospitals in Australia have less than a week ’s supply. Strategies are therefore urgently needed to conserve ICM for those diagnostic tests and interventions which are time-critical, and without which patients would suffer death or significant morbidity. A plan is also required to continue providing best-possible care to patients in the wors t-case scenario of exhausted ICM supplies. This document, by representatives from two major public hospitals, will provide some guidance that is ta...

Diagnostic imaging for suspected pulmonary embolism during pregnancy and postpartum: A comparative radiation dose study
ConclusionsCompared to V/Q, CTPA is associated with higher maternal and breast radiation dose; however, modern CT scanners achieve lower radiation doses than historically described. Fetal radiation dose was comparably low. The diagnostic yield of the imaging modalities in pregnant and postpartum women is similar. Revision of guidelines should occur with the advances in CT technology. (Source: Journal of Medical Imaging and Radiation Oncology)

Machine learning imaging applications in the differentiation of true tumour progression from treatment ‐related effects in brain tumours: A systematic review and meta‐analysis
ConclusionTRE can be distinguished from TTP with good performance using machine learning-based imaging models. There remain issues with the quality of articles and the integration of models into clinical practice. Future studies should focus on the external validation of models and utilize standardized criteria such as CLAIM to allow for consistency in reporting.

Failure to attend radiation oncology appointments during COVID ‐19: Analysis of data from an Australian public hospital
ConclusionAttendance for radiation oncology treatment was largely unaffected by COVID-19 although other services experienced slight reductions. Changes to work practices, specifically the increased use of telehealth, may have moderated the impact. Given the focus on one service in one location, it is not possible to generalise these results and future research should closely monitor both patient and staff satisfaction with services delivered via modified processes.

Role of radiomics in predicting immunotherapy response
SummaryImmunotherapies have revolutionised cancer management. Despite their success, durable responses are limited to a subset of patients. Prediction of immunotherapy response in patients has proven to be difficult due to a lack of robust biomarkers. Routinely collected imaging may offer an additional information source to personalise patient treatment, with advantages over tissue-based biomarkers. Quantitative image analysis or radiomics, which involves the high-throughput extraction of imaging features, has the potential to non-invasively predict cancer histology, outcomes and prognosis. This review evaluates the value ...

Survey of brachytherapy training experience among radiation oncology trainees and fellows in the Royal Australian and New Zealand College of Radiologists (RANZCR)
ConclusionThis is the first survey on brachytherapy training experience among RANZCR trainees and fellows. It highlighted limited brachytherapy exposure during RANZCR training, and the need to revisit brachytherapy training requirement in the current training programme, along with long-term brachytherapy workforce planning.

ROLLIS roll ‐out: Pitfalls, errors, lessons learned and recommendations from Australian and New Zealand experience during the randomised controlled trial, implementing a novel localisation method for impalpable malignant breast lesions, radio‐guided occult lesion localisation with iodine‐125 (125I) seed ( ROLLIS)
ConclusionThe Australian and New Zealand ROLLIS RCT experience highlights the need for adherence to local licencing laws and protocols, appointing a dedicated ROLLIS Designated Team Lead with good communication and a ROLLIS Co-ordinator. These facilitate the adoption of a successful ROLLIS programme. (Source: Journal of Medical Imaging and Radiation Oncology)

Evaluation of a national database of completed investigations into radiology service complaints in New Zealand: What can the radiologist, and radiology service providers, learn?
ConclusionErrors in radiology practice, leading to complaints, are often multifactorial and systemic. Reflection on the myriad of error types and contributing factors (including ‘human factors’) is imperative to reduce errors. Multifaceted strategies are likely required for radiologists to enhance their systems and practice. (Source: Journal of Medical Imaging and Radiation Oncology)

Previously unreported variant collateral supply in an acute stroke patient with anomalous common and internal carotid artery anatomy undergoing mechanical thrombectomy
SummaryAgenesis of the common carotid and internal carotid arteries are rare entities. Approximately 100 cases of internal carotid artery (ICA) agenesis are reported in the literature, and even fewer cases of common carotid agenesis. The collateral supply in such cases is well described and typically follows one of only a small number of variations. Lie classically described six major pathways of collateral supply in ICA agenesis (Congenital Anomalies of the Carotid Arteries. Excerpta Medica, Amsterdam, 1968; 35). Vasovicet  al. in a comprehensive review of all published cases of common carotid agenesis have similarly des...

Magnetic resonance imaging features of prostatic stromal tumour of uncertain malignant potential
ConclusionMRI features of STUMP are presented as regular, well-defined and isolated prostatic mass with intact pseudocapsule. The presence of heterogeneous T2WI signal, intratumoral cystic change, slightly low mean ADC value and persistent or gradual enhancement may help predict the STUMPs.
